Although the difference of the brands and models exists, the principle and function of mobile phone and mobile charger are similar, and their circuits are also resemblance. The entire mobile phone charger contains a constant voltage source and some circuits that contains the constant current, limit voltage or limit time. In this thesis, an intelligent charger with the center of MCU and a charge chip MAX1898 is elaborates. The main task of the project is the design and realization of an intelligent phone charger based on the MCU. The emphasis of this thesis contains two parts: first, realization of charge, second, realization of intelligence. There are five chapters composed this thesis. The first part is preface. It elaborates the knowledge about battery, charger and how to charge the battery. It also introduces the task of the project and the purpose of this design. The second part introduces the hardware construction of the designed intelligent mobile telephone charger for Lithium battery. It is one of the emphases of this thesis. It introduces the desig
